我按照express.js指南中显示的方式安装快递。 http://expressjs.com/guide.html

运行'node app'后，我收到此错误：

   /Users/xxx/Documents/work/node/app.js:3
    var app = express();
              ^
    ReferenceError: express is not defined
        at Object.<anonymous> (/Users/xxx/Documents/work/node/app.js:3:11)
        at Module._compile (module.js:449:26)
        at Object.Module._extensions..js (module.js:467:10)
        at Module.load (module.js:356:32)
        at Function.Module._load (module.js:312:12)
        at Module.runMain (module.js:492:10)
        at process.startup.processNextTick.process._tickCallback (node.js:244:9)

Answer 1

您需要var express=require('express');之类的内容才能定义express。你引用的链接提到了这样做;也许你已经过了一两步（比你想象的要容易得多）？
